Zur Bildung wasserlöslicher Polysalze. 4. Mitt.: Untersuchungen zum Übergang vom löslichen Symplex zur Polysalzfällung
Abstract: Der Übergang von makroskopisch löslichen Polyanion‐Polykation‐Komplex (Symplex) zur Polysalzfällung wird mittels Kombination von Potentiometrie, Konduktometrie und Turbidimetrie untersucht. Als Ausgangsmaterialien dienen vor allem Cellulosesulfat und Polyethylenimin sowie anionisch und kationisch modifizierte Polyacrylamide. Unter den angewandten Bedingungen wurden bei elektrochemischer bzw. bei turbidimetrischer Endpunktanzeige nur in wenigen Fällen 1: 1‐Symplexe erhalten. Die Endpunkte und der Verlauf der Tr…

“…Systematic studies of various parameters influencing the structure of quasi-soluble complexes, was undertaken by Philipp − using light scattering. The concentration of polyelectrolyte solutions, degree of conversion, salt content of the medium, polymer charge density and ionic strength of the solution were varied in order to study the nature of complex formation between latices and polyelectrolyte chains.…”
